GPIB-wifi: common questions
What microcontroller does the GPIB-wifi use?
The GPIB-wifi is built around the ESP-12/07v2/08v2, from the ESP8266 family.
How big is the GPIB-wifi PCB?
The GPIB-wifi measures 63 × 65.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the GPIB-wifi?
105 components, from 30 distinct parts. The full bill of materials is listed on this page.
Where can I download the GPIB-wifi design files?
From the bitdivision/GPIB-wifi-pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the GPIB-wifi design in my own project?
The repository has no license, so all rights stay with bitdivision. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the GPIB-wifi without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
